IMPROVEMENT IN THRASHlNG-MACHINES.

Specification forming part of Letters Patent No. 175,873, dated April 11, 1876; application filed February 7, 1876.

To all whom it may concern:

Be it known that I, CHRISTAIN L. POORMAN, of Bellaire, Belmont county, in the State of Ohio, have invented an Adjustable Side Han ger for Miter-Gear Shaft on Thrashin g-Machines, of which the following is a specification The object of myinvention is to rapidly and conveniently change the line of the miterwheel or side-gear shaft on a thrashing-machine from a horizontal position to any desired angle, without changing the working re 'lation of the dogs or teeth on the miter-gear wheels, thereby making the line of the mitergear shaft conform to the line of tumblingrod, or shaft running from horsepower to thrashing-machine, and reducing the friction and wear of the coupling by which the sidegear shaft and tumbling-rod are joined.

The following is afull and accurate descrip tion of my invention, reference being had to the accompanying drawings, making part of this specification.

Figure 1 is a plan view of the hanger, shafts, and miter-wheels as in use when set at an angle; Fig. 2, a face view of the inner part of the hanger, showing the radiating grooves and slotted holes for bolts; Fig. 3, a back View of the outer part of the hanger, showing the tongues or Vs corresponding with the radiating grooves in Fig. 2, and the boltholes, 850. Y

The main features of my invention consist in 1 the two parts, Fig. 2, bolted to the machine as a base for the parts shown in Fig. 3, and Fig. 3, containing the bearings for miter-gear shaft, and the radiating grooves a a, Fig. 2, the radiating tongues or Vs b b, Fig. 3, and the slotted holes a c, Fig. 2.

The plate 0, Fig. 2, which is the base to be bolted t the machine, is provided with elevated flanges, on the outer face of which are radiatin g grooves a a, which are formed bydrawing diverginglines from the center of the throughshaft h, as shown in Fig. 1, to the front of plate 0 at f, and the slots 0 c, the screwthreaded bolts or rods d, which secure plate 0 to the frame, the slots 0 0 being made in the form of arcs of circles drawn from the center of shaft h, and hanger D being secured in place by tightening the nuts on the bolts (1.

The hanger D, Fig. 3, which contains the bearings for the miter-gear shaft A, has upon its upper inner edge tongues or VS 1) b, corresponding with and made to fit into the radiating grooves are in plate 0. The tongues b b, when the hanger D is attached to the plate 0, are intended to fit into any of the grooves a a, and keep the shaft A, to which is attached miter-wheel B, in working relation to the through-shaft h, no matter at what angle of depression the short shaft A may be placed.

I claim as my invention 1. The combination of plate 0, formed with radiating grooves a a, and hanger D, provided with the tongues b b, substantially as and for the purpose set forth.

2. The plate 0, formed with radiating groovesa a and arc-formed slots 0 c, in combination with the hanger D, having the tongues b b and bolts 01, substantially as set forth.
